The hair brightening compositions of the invention comprise certain hair brightening activating salts and organic colorants as active brightening ingredients which surprisingly remove discoloration without imparting an unnatural tone to the hair. The inventive hair brightening compositions provide a significant improvement over conventional prior-art hydrogen peroxide-based hair brightening compositions in effectiveness, are less damaging to the hair, and more varied in their useful product forms. The invention is also directed to compositions and methods for alkali relaxing and brightening hair, especially naturally gray hair, and single-use kits comprising the inventive hair brightener compositions.
